However, the website infektionsschutz.de, a site of the Federal Centre for Health Education, assures: Whether cold or warm water is used for hand washing is not relevant.

Using soap helps

Soap should not be avoided. For one thing, surfactants kill the germs on our skin and make our hands thoroughly clean.

Infektionsschutz.de advises washing your hands especially after visiting the toilet, before eating, after coming home and after contact with animals.
